Abstract: 1,252,140. Change speed control; cams. VOITH GETRIEBE K.G. 24 Dec., 1968 [28 Dec., 1967], No. 61440/68. Headings F2D and F2K. A control for a motor vehicle change speed gear having a torque converter 2 in series with a planetary reverse gear 3, 4 and a change speed gear 5, 6 comprises a shift lever 16 fast with a rotatable plate 17 having a face valve 18 controlling the supply of ratio establishing pressure liquid to the reverse gear 3, 4 and a cam 21 acting through a follower lever 22 on a valve spool 25 of a follow-up servomotor 26 controlling a valve ring 43 which is axially slidable into the working circuit of the torque converter. In a central, neutral, position of the plate 18 both the forward and reverse ratio establishing servo lines 19, 20 are vented. Initial rotation of the plate 17 supplies pressure liquid to the line 19 or 20 to establish forward or reverse ratio and thereafter on further rotation of the plate 17, the cam 21 causes withdrawal of the valve ring 43 from the working circuit to increase the torque converter capacity. When the torque converter capacity is a maximum an output speed responsive control 10 upshifts the change speed gear 5, 6. In high ratio the control 10 supplies pressure liquid to engage a torque converter lock-up clutch 7 and additionally supplies pressure liquid through a valve 31 to a piston 30 which moves left the servomotor valve spool 25 whereupon the servomotor 26 moves the valve ring 43 into the torque converter working circuit. The leftward movement of the valve spool 25 is permitted by the support 32 of the follower lever 22 yielding against the force of a spring 33. Movement of the valve 31 to the position A blocks the supply to the piston 30 and another valve (not shown) renders the control 10 inoperative to enforce low ratio. In the position R the valve 31 connects the piston 30 to an output driven pump 9 having a restricted leak-off 41 to provide output speed responsive control of the valve ring 43.

Abstract: 1290091 Automatic gain control RCA CORPORATION 2 March 1970 [3 March 1969] 9873/70 Heading H3T In a television A.G.C. arrangement in which the gain control voltage is derived from the sync. pulses, means are provided for inhibiting the derivation of gain control voltages from accompanying impulsive noise. Video signals in which sync. pulses comprises the most negative component are derived from video amplifier 20 over a cascade emitter-follower 21a, 21b and are applied to the base of transistor 34 over resistors 60, 62. In the absence of a video signal transistor 34 is biased to saturation and its collector-emitter path biases a second transistor 38 to cut-off. The collector-emitter path of transistor 38 shunts resistor 42 in a potentiometer network 42, 44 from which the first I.F. amplifier 12 is biased over resistor 48, and in the absence of video signal no effective shunting occurs. The base of transistor 38 is impulsed with line flyback pulses from source 50 via levelsetting resistor 53, Zener diode 52 and resistors 36, 54, and when the shunt on its base-emitter circuit formed by transistor 34 is removed by the impulsing of the latter by the negativegoing sync. pulses, transistor 38 becomes conductive, shunting resistor 42 and so reducing the base bias of I.F. amplifier 12. The bandwidth of the A.G.C. circuit is determined by capacitor 56 connected between collector and base of transistor 34. Noise impulses derived over resistor 60 are differentiated by differentiating circuit 88, 86 and are applied over transistors 74, 76 to the base of transistor 78 which acts as a clamp, preventing the application of a line flyback pulse from source 50 to the base of transistor 38 for the duration of a noise pulse.
